In West Virginia, 100 days of the year (365)have temperatures less than32 degrees Fahrenheir. What (reduced) fraction of the days is that?

• College Math -

well, just write

100/365

obviously 5 divides both top and bottom, so divide it out to get

20/73

Since 73 is prime, it has no factors in common with 20, so that's as far as you can go.

• College Math -

100 out of 368 days =

100/365 = 20/73

• school math -

20.73
